Class EvalException

java.lang.Object

java.lang.Throwable

java.lang.Exception

jdk.jshell.JShellException

jdk.jshell.EvalException

All Implemented Interfaces:

Serializable

public class EvalException
extends JShellException

Wraps an throwable thrown in the executing client. An instance of EvalException can be returned in the SnippetEvent.exception() query. The name of the throwable thrown is available from getExceptionClassName(). Message and stack can be queried by methods on Exception.

Note that in stack trace frames representing JShell Snippets, StackTraceElement.getFileName() will return "#" followed by the Snippet id and for snippets without a method name (for example an expression) StackTraceElement.getMethodName() will be the empty string.

final void	addSuppressed(Throwable exception)	The specified exception is going to be suppressed in order to give priority to this exception (primary exception) and to be appended to the list of suppressed exceptions.
Throwable	fillInStackTrace()	Record in the receiver a walkback from the point where this message was sent.
String	getLocalizedMessage()	Answers the extra information message which was provided when the throwable was created.
String	getMessage()	Answers the extra information message which was provided when the throwable was created.
StackTraceElement[]	getStackTrace()	Answers an array of StackTraceElement.
final Throwable[]	getSuppressed()	Returns an array of exceptions suppressed, typically by the automatically generated code from the try-with-resources statement, in order to give priority to this exception (primary exception).
Throwable	initCause(Throwable throwable)	Initialize the cause of the receiver.
void	printStackTrace()	Outputs a printable representation of the receiver's walkback on the System.err stream.
void	printStackTrace(PrintStream err)	Outputs a printable representation of the receiver's walkback on the stream specified by the argument.
void	printStackTrace(PrintWriter err)	Outputs a printable representation of the receiver's walkback on the writer specified by the argument.
void	setStackTrace(StackTraceElement[] trace)	Sets the array of StackTraceElements.
